i want to keep the DIC

I Already Looked In To That Kit. I Dont Want To Remove The Dic Because It Looks Ugly Without It And I Dont Want To Spend More Money In Another Stereo With Double-din Size Screen.THAT THE STEREO I HAVE.

Having done a few Caddy's in my day, my first question is does it have the bose stereo. And if so, did you know you're gonna have to remove/replace all your speakers and amps. If I remember correctly the radio/DIC integration in those cars requires some skill to separate.

Also you might be able to get better answers to your questions over on the caddilacforums.com board. Jason is the audio moderator over there and is quite knowledeable. There is one good tutorial on modding the CTS that I know of from MBai on cadillacforums. His webpage is here.

If you're not installing a CarPC, this probably isn't where you need to be (a Kenwood In-dash DVD doesn't come close).
